摘要： A coin identification circuit including a coil configuration defining a coin detection region, disposed in a first sub-circuit for supplying electrical current to the coil configuration. The circuit includes means to modify the electrical current being supplied to the coil configuration when a coin is in the detection region, whereby to trigger a first decay pulse characteristic of the coin in a second sub-circuit including the coil configuration. Means are included to at least partially integrate the first decay pulse, whereby to derive a further integral decay pulse of small amplitude range relative to the first decay pulse. The circuit also includes means to measure sufficient parameter values for the integral decay pulse to identify the coin. A method of identifying a coin or of discriminating between two or more coins is also described.

摘要： Un système de validation de pièces de monnaie (10) possède un circuit de pièce (26) qui passe entre un ensemble de bobines de détection (40, 42). L'ensemble de bobines (40, 42) est relié à un circuit de détection et les bobines (40, 42) sont conçues pour être excitées par une impulsion unique. La courbe de décroissance (70) de la tension des bobines (40, 42) est traitée pour produire un ensemble de trois nombres de comptage d'horloge définissant chacune des pièces, mémorisés dans un microprocesseur. La pré-programmation du système de validation (10) comprend la génération d'ensembles de nombres pour des exemplaires représentatifs d'un type de pièce afin d'obtenir trois gammes de nombres, un ensemble de nombres correspondant à une pièce introduite successivement devant se situer à l'intérieur de la gamme de nombres respective pour que la pièce soit indentifiée et validée. Le circuit de pièce (26) est conçu pour former un angle avec la verticale et la base (32) est conçue pour former un angle avec l'horizontale de façon que l'angle situé entre une paroi (36) et la base (32) se trouve entre 90° et 180°, ce qui permet aux pièces passant dans le circuit (26) de s'orienter pour que chacune d'entre elles possède un point de contact situé sur la base (32) et l'une des parois (36), occupant, de ce fait, une position généralement similaire par rapport aux bobines (40, 42).

摘要： Coin validation can be advantageously improved by transforming measured data values associated with coin characteristics from a first geometric space to a second geometric space, in which the transformed values in the second geometric space are preferably better adapted for discrimination between different coin denominations than the corresponding values in the first geometric space. Preferably, principal component analysis is used to identify principal components that can be used as dimensions of the second geometric space, so that measured data values in the second geometric space are less correlated than in the first geometric space.

摘要： A method of categorising coins/tokens by energising detect coils with a single pulse detecting the back EMF curve of the decaying pulse information, analysing the unmodified back EMF curve to extract therefrom a number of variables and processing those variables to provide values proportional to the variables and, comparing the values of the coin/token with at least one of a number of reference values to determine into which of a number of predetermined categories the coin/token falls.

摘要： A coin validator (10) has a coin path (26) which passes between one set of detect coils (40, 42). The set of coils (40, 42) is connected in a detect circuit, and the coils (40, 42) are adapted to be energised with a single pulse. The decay curve (70) of the voltage in the coils (40, 42) is processed to produce a set of three numbers of clock counts defining each coin, which are stored in a microprocessor. Pre-programming of the validator (10) involves generating sets of numbers for representatives of a coin type to create three ranges of numbers, within which respective range subsequent coin's set of numbers must fall in order for it to be defined as an example of the coin type. The coin path (26) is arranged at an angle to the vertical, and the base (32) is arranged at an angle to the horizontal such that the angle between one wall (36) and the base (32) is between 90° and 180°, causing coins passing along the coin path (26) to orient themselves such that each of them has point contact on the base (32) and on the one wall (36), thereby occupying a generally similar position with respect to the coils (40, 42).
